ServerWorks chipset

In case this helps...
I have a pre-release server under NDA. I'm not positive if this is the
chipset you're interested in. The output from lspci:
00:00.0 Host bridge: Relience Computer CNB20HE (rev 06)
Flags: bus master, medium devsel, latency 48
00:00.1 Host bridge: Relience Computer CNB20HE (rev 06)
Flags: bus master, medium devsel, latency 48
Here's a streams run (I have a modified streams which uses the Intel cpu
clock, in case you're wondering about the extra lines. The higher
precision from this clock gives more accurate results w/out resorting
to huge array sizes):
lrep3:~/benchmarks/streams$ ./streams
-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 4000000, Offset = 0
Total memory required = 91.6 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Cycles/second = 731012878.228893
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 119432 microseconds.
(= 119432 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.
-------------------------------------------------------------
Function Rate (MB/s) RMS time Min time Max time
Copy: 405.2265 0.1580 0.1579 0.1584
Scale: 403.5475 0.1586 0.1586 0.1587
Add: 512.4053 0.1874 0.1874 0.1874
Triad: 353.2453 0.2718 0.2718 0.2719
Currently the machine has 4 128-MB 133MHz DIMMs. Sorry, I don't have
the precise timings at hand. I'd originally run streams w/only 1 DIMM
installed, and got a disappointing number (about 350 for Copy, I think).
I'd guessed the machine had interleaving when I added the additional
DIMMs. I'm away from the lab until Monday, but I'd be happy to report
additional measurements.
